Abstract

The invention provides a method for preparing a cylindrical box body for deep-sea net cages with antifouling properties, including A, preparation of antifouling net clothing, including preparation of modified high-density polyethylene composite materials, preparation of antifouling monofilament bundles, and antifouling Three aspects of dirty net processing; B. Anti-friction net preparation, made of polyamide net coated with polyurea coating; C. Cylindrical box preparation, including side net processing, bottom net processing and cylindrical box Three aspects of processing. According to the preparation method of the present invention, the cylindrical box body with antifouling performance for deep-sea net cages can greatly improve the antifouling performance of the cylindrical box body under the premise of keeping the strength of the side nets constant. It can also reduce the water resistance of the cylindrical box and the area of ​​fouling organisms, which can greatly reduce the fouling of the cylindrical box and the fish escape accidents caused by broken nets under harsh sea conditions. Green development and modernization.

Description

technical field

[0001] The invention belongs to the technical field of deep sea net cages, and in particular relates to a preparation method of a cylindrical box body for deep sea net cages with antifouling performance. Background technique

[0002] China is currently the world's largest aquaculture country, but the future growth space of aquaculture industry is worrying. In order to meet the above challenges, people are focusing on deep-sea cage culture. Deep-sea net cages refer to those placed in open waters with a depth of more than 15m at low tide and large currents, or in waters off islands and reefs three nautical miles offshore, or in aquaculture waters not less than 1000m 3 seawater cages. In recent years, a number of units have built various forms of deep-sea cages to realize the green development of deep-sea cages.

[0003] "Case body", "side net", "bottom net", "edge net", "net net" and "net clothing" are all nouns in the technical field of deep sea net cages. ...
